T0 a/ZZ whom, t may conce/7L;

Be it known that I, HERBERT ERNEST NEW- TON MASON, a subject of the Queen of Great Britain, residing at Birmingham, England, have invented certain new and useful Improvements in Lamps for Burning Light or Volatile Oils, (for which I have obtained Letters Patent of Great Britain No. 8,709, dated .Tune 5, 1890;) and I do hereby declare that the` following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention has reference to lamps for burning light or volatile oils in which a small oil-container or Wick-dipping cup at the head of the lamp is supplied with oil from a storage-reservoir in the base or body of the lamp; and my said invention consists principally of the construction and combination of parts hereinafter described and claimed for filling the said oil-container or wick-dipping cup from the storage-reservoir.

My invention is applicable to table-lamps and to standard lamps, or lamps supported on the floor.

I will first describe my invention as applied to a table-lamp. The case or body of the lamp constitutes a large storage-reservoir for the oil, and above the said storage-reservoir and on the axis of the lamp a small oilecontainer or dipping-cup is supported. In the base ofthe storage-reservoir and communicating with it by a series of perforations is a hollow cylinder in which a piston works. By means of the said piston, worked by the mechanism hereinafter described, the oil in the cylinder is forced through a supply-pipe opening into the bottom of the cylinder to the oil-container or dipping-cup. The overflow-pipe from the oil-container or dippingcup is arranged concentrically around the greater part of the oil-supply pipe and opens into the storage-reservoir.

The piston in the cylinder is worked by the following mechanism: The piston-rod passes through a long guide-tube in the axis of the oil-reservoir and its upper end is jointed to the lower end of a crank-rod the upper end of which is jointed to a crank-pin on the face of a toothed wheel turning in bearings above the oil-reservoir. This crank toothed wheel gears with and is rotated by a pinion situated above it and working on a parallel axis. The axis of the pinion projects from the lampcasc and has a square end for turning the the said pinion rotatory motion is given to the crank toothed wheel and the said wheel, through its crank-pin and crank-rod, gives a reciprocating rising and falling motion to the piston-rod and piston. by the said piston from the cylinder in communication with the storage-reservoir and through the oil-supply pipe toV the oil-container or wick-dipping cup.

I will now proceed to describe with reference to the accompanying drawings the details of my invention and the manner in which my invention is to be performed.

Figure l represents in vertical section a table-lamp containing myimprovements. Fig. 2 represents in vertical section a portion of the same taken in a plane at right angles to that in which the section Fig. l is taken. Fig. 3 represents in section a portion of the concentric oil-supply and overflow pipes of the lamp, and Fig. fi in section the upper part of the lamp drawn to a larger scale.

The same letters indicate the same parts in the several figures of the drawings..

a is the storage-reservoir for the oil, filled at an opening at a2 in the top of the said reservoir, and b is the small oil-container or wickdipping cup at the top of the lamp.

c is the hollow cylinder in the base of the storage-reservoir a, and CZ is the piston working in the said cylinder and actuated in the manner hereinafter described. By means of the slots or perforations at c communication is established between the storagereservoir a and cylinder c for the passage of oil from the former into the latter.

ff2 is the oil-supply pipe, through which oil cylinder c. The said oil-supply pipeffz opens at bottom into the cylinder c, and passing upward enters the wick-dipping cup or oil-containerbthrongh the tubular base ofthe same.

g g2 is the overflow-pipe from the oil-container h. It will be seen that the said overiiow-pipe is arranged concentrically about the said pinion by a key or winch. By rotating` is forced by the action ot' the piston d in the' Oil is thereby forced IOO greater part of the oil-supply pipe and opens at h into the storage-reservoira. The tops of the said concentric oil-supply and overflow pipes are connected together by the hollow perforated sphere i', the oil from the supplypipe passing outinto the contai ner by the perforations 7a in the said sphere. Portions of the top ot the overflow-pipe g2 between it and the sphere are cutaway at Zto permit ofthe overliow-oil entering the said overflow-pipe and returning` by the said pipe to the storage-reservoir, as best seen in Fig. 3.

In the base of the wick-dippingcup or oilcontainer Z) is a tubular passage b2 for receiving the concentric oil-supply and overflow pipes f2 g2.

For the purpose of adjusting the height of the concentric oil-pipes in the wick-dipping cup or oil-container b I make the upper parts of the said pipes telescopic, in the manner best seen in the enlarged view, Fig. S-that is to say, the upper part g2 of the overfiowpipe is made separate from the lower fixed part g of the said pipe, and the two parts g g2 are connected together and a tight joint made between them by means of the tubular collar or sleeve m, the lower part of which is soldered to the part g of the overow pipe. Within the upper part of the collar or sleeve m the adjustable upper part g2 of the overlHow-pipe is capable of sliding. Similarly the upper part f2 ot' the oil-supply pipe is separate from. the lower tixed part f, and the two parts are connected by the tubular collar or sleeve n, soldered to the lower part f, the upper adjustable part f2 being capable of sliding in the said collar or sleeve n. By sliding the pipes f2 and g2 within their respective sleeves 'n and m the height of the oil-supply and overiiow pipes in the wick-dipping cup or oil-container b may be adjusted.- As the two pipes are connected together at top by theperforated sphere i, the raising or lowering of the outer pipe in its sleeve m at the same time raises or lowers the inner pipe in its sleeve n.

The adjustable upper parts f2 and g2 of the oil-supply and overflow pipes are iixed to the oil-container b and the said oil-container to the top of the lamp in the following manner: p is a metal socket or cup having' an external screw-collar p2. In the axis of the socket or cup p the pipes f2 g2 are placed, and after the tubular bottom. h2 of the oil-container has been placed in the socket and the pipes adjusted at the proper height the whole of the parts are secured in the socket by cement at nut p5 is screwed upon a collar on the outer pipe g2 and made to bear against the bottom of the socket. A liquid-tight joint is thus made between the tubular bottom b2 of the oil-'container b and the concentric pipes passing through it. The pipes f2 g2 being thus secured to the oil-container, they are introduced into the collars m n and the socket or cup p screwed by its collar p2 into the top `ot the neck ot the lamp, the pipes f2 g2 sliding in the collars m n as the socket p is screwed home. The neck of the lamp is packed with a packing of cork p6 to prevent the escape of oil, on the upsetting of the lamp, between the storage-reservoir and the oil-container.

The piston d, by the reciprocating motion of which in the cylinder c the oil in the said cylinder is forced through the oil-supply pipe ffg into the wick-dipping cup or oil-container b, is actuated by the following mechanism: d2 is the piston-rod, and d3 is the crank-rod, jointed to its upper end di. The upper end d4 of the piston-rod is cylindrical and works in the cylindrical guide-tube q, which tube is slotted on opposite sides to permit of the motion of the crank-rod d3. The stem or reduced part of the piston-rod head (Z4 is connected by a ball-and-socket joint at d5 to the piston d. By connecting the piston-rod with the piston by means of a ball-and-socket joint instead of a rigid connection the piston is capable of slight play on the piston-rod, and hence can perform its reciprocating motion in itscylinder without undue wear and strain. The upper end of the crank-rod d3 is jointed to the crank-pin r2 on the face of the toothed wheel r, the axis of which turns in the bearing at r3, supported at the top of the case or body of the lamp. The crank toothed wheel r gears with and is rotated by the pinion s, situated above it and working on a parallel axis s2, the said axis of the pinion being worked from outside the lamp-case by the key t, taking upon a square end on the axis of the pinion.

When it is wished to till the dipping-cup or eil-container b with oil from the storage-reservoir a, the pinion s is rotated by its key t i and a rotary motion given to the larger ,crankwheel r. This motion is transmitted through its crank-pin r2 and crank-rod d3 to the piston- `rod d2 and piston d, and a reciprocating motion thereby given to the said rod and piston,

3 and the oil in the cylinder c, supplied thereto i from the storage-reservoir d, is forced by the said piston from the said cylinder up the supply-pipe ff2 to the oil-container or wick-dipping cup b, the surplus oil supplied to the Adipping-cup being returned to the storagereservoir through the overflow-pipe g g2.

I do not limit myself to the particular arlrangement of toothed wheel and pinionv described and represented for working the pisf ton, as other equivalent arrangements of gearfing may be used for that purpose.
